FIELD: radio engineering, possible use in information transfer systems with hopping working frequency.
SUBSTANCE: in accordance to method, in known method during transfer of information transformations of information series into decimal numbers are performed, which numbers determine code of pseudo-random series and bearing frequency of transmitter; signal generated on basis of pseudo-random series code is modulated by frequency, synchronized on basis of bearing frequency of transmitter; during receipt by means of frequency filtration channel is selected, by means of which transmission occurred, maximal value of peak of autocorrelation function is determined, which value is used to determine pseudo-random series code, from which by means of serial reverse transformations decimal number is received, which is transformed to binary form appropriate for transferred information.
EFFECT: increased resistance to interference, provision of information and structural concealment of message being transferred.
